Mean and Standard Deviation of the Sampling Distribution
Hi, I'm really having trouble with this math homework! Help please!

A machine automatically dispenses a beverage of a desired size. When set to "small," the machine dispenses varying amounts of liquid with a mean of 275 mL and standard deviation of 10 mL. Suppose that we take random samples of 5 of these drinks and calculate the mean amount of liquid x¯ in each sample. We can assume that individual drinks are independent.

Calculate the mean and standard deviation of the sampling distribution of Calculate the mean and standard deviation of the sampling distribution of x¯.

x¯.

μx¯​= ____ mL a.) 275 b.) 280 c.) 10 d.) 555

σx¯= ____ mL a.) 10 b.) 3472 c.) 4.0 d.) 4.472
